An advanced control system for a gas turbine needs an adaptive function which is called Performance Seeking Control (PSC) . PSC technology includes the engine model update logic and the optimization of the control laws. Using PSC, it is possible to adapt control laws for off-nominal design conditions, for example, various flight conditions, engine performance deteriorations and component variations among engines and so on. The most important thing for an adaptive system like PSC is to confirm that the control will not run out of the proper control. For this reason, it is necessary to assess stability and performance of an adaptive system exactly. In addition, the soft-ware for the assessment and a tuning of control must be simple enough to be implemented in an a p paratus. In this paper, a parameter method which analyzes and assesses a control system is mentioned. This is suitable for an adaptive system of a gas turbine. The identification of a gas turbine model using the ARMA model and Kalman filter, and auto tuning method of control parameters of the control system of a gas turbine, and experimental results of the adaptive control system of a gas turbine are mentioned.
